it will be impossible M the loom operator may move 40* front end of theI screw isthe contactmember "75 which'is adaptedto cooperatewith therearend 860i the shuttle boxextensio'n21. The arm*70'is'provided withthepin1'76 and the plate isprovided with a pin '77; betweenwhichis-connectedthecoil-"spring '78 for drawing the arm '70 and thelatch bar 50 in counterclockwise direction, as shown in Fig. 2.

In operation, when the loom is stopped and the shipper lever 31 is movedto inoperative position, as indicated by the dotted lines on Fig. 1, theclutch operating rod 36 will be moved rearwardly permitting the spring78 to draw the bar 50 downwardly so that the notch 58 will engage withthe block 60 and the dog 6'7 will be received in the notch 5'7, providedthe lay is not at or adjacent its rearmost position 30.

When the necessary adjustment has been made to permit the loom tocontinue to operate, as for example, the replacement of the filling inthe shuttle or the connection I of the broken weft and/ or warp threads,or mechanical adjustments due to derangements of the operatingmechanism, for the loom operator or weaver to start the loom with thelay in its intermediate position, due to the fact that the clutch rod 36would be firmly held in rear position due to engagement of the latch 60and the notch 58.

The weaver or loom operator will then have to actuate the wheel 42, orsome other suitable mechanism to move the lay rearwardly tosubstantially its back-center position, at which time the contactelement 86 on the shuttle box extension 21 will contact with on thescrew '73.

This contact, as indicated in Fig. 4, will lift the notch 58 from thelatch 60 so that there will no longer be engagement therebetween,whereupon the shipper lever 31, initiating operation of the loom.

The dog 6'7 at this time will be pulled forward to contact with thesloping edge 69 of the notch 5'7. This will further elevate the bar 50and move the lever '70 still farther backwardly so that the contactelement '75 will not contact with the 86. The engagement of the 69 ofthe notch 5'7 will also 50 out of engagement shuttle box element dog 67with the edge assure locking of the bar with the latch 60.

It is thus apparent that the loom operator or weaver may only start theloom when the lay has been moved to its back center position andassurance is had that the last filler thread before such stoppage willbe beat up with the proper force 55- and stress into position at thefell of the woven fabric.

The device of the present invention eliminates need for rigidsupervision of weavers, and particularly of the apprentice weavers toassure production of crack-free merchandise, and also greatly reducesthe cost of maintenance of the loom, inasmuch as it is not necessary tobe absolutely certain that all bearings are adjusted without play andthat the clutch linings are in perfect condition.

3 Claims.

This invention relates to new and improved mechanism whereby motorvehicles may be more conveniently and economically stored within abuilding designed for the housing of such vehicles such, for instance,as a public garage.

Another object of the invention is to provide new and improved mechanismwhereby a greater number of motor vehicles may be deposited or storedupon a given floor space than has obtained in mechanisms of thischaracter as hitherto constructed.

Another object of the invention is to provide mechanism for storingmotor vehicles such that the danger of vehicles being carried intocontact with each other and thereby damaged during the movement of suchvehicles on the storage floor of the garage is eliminated.

.A further object of the invention is to provide new and improvedmechanism for storing motor vehicles and a new and improved system forthe distribution and checking of the stored vehicles, whereby the garageowner andthe patrons are afforded a greater degree of protection againsttheft, unauthorized removal and unauthorized use of the motor vehicleswhile in storage.

A still further object of the invention is to provide a new and improvedconstruction of the floor of a garage whereby motor vehicles can bemoved to and deposited in their designated spaces with the expenditureof a minimum amount of manual labor.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following'description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention, and the scope of protection contem-= platedwill be indicated in the appended claims.

In the accompanying drawings wherein I have illustrated a preferred formof embodiment of my invention:

Figure 1 is an elevational view of the ground or entrance floor of agarage constructed in accordance with my invention;

Figure 5 is an elevational view of one of the storage spaces showing thetable or carrier in operative relation therewith;

Figure 6 is a vertical elevational view of Figure 5 taken substantiallyon a line 5 -5;

Figure '7 is a schematic view showing certain of the control devices;

Figure 8 is also a schematic view showing another of the controldevices;

Figure 9 is also a schematic view showing another of the controldevices;

Figure 10 is a view partly in section and partly in elevation showing adetail of construction;

Figure 11 is an elevational view of Figure 10; and Figure 12 is a viewon an enlarged scale of the clutch mechanism associated with the motorvehicle carrying table.

Referring now to the drawings wherein similar reference characters referto similar parts throughout the several views thereof, the referencenumerals 1, 2, 3 and 4 represent the walls of a typical shaped garage,and 5 denotes the ground floor thereof, to which access may be hadthrough one or more doors not shown. The reference numerals 6, '7, 8, 9and 10 denote a plurality of elevator shafts in each of which operatesan elevator 11; 12 denotes a stairway which, as usual, is locatedadjacent one or more of the elevator shafts.

For purposes of this specification, the floor space 5 will be designatedthe classification floor; that is to say, it is the floor upon which themotor vehicles are driven and their storage destination classified by anemployee of the garage owner, whereby the distribution of the motorvehicles will be such that a maximum number of them will be deposited inthe various fioor spaces provided upon the several floors of the garage.It is intended that vehicles of predetermined sizes shall be classifiedso that they will be stored together.

The reference character F denotes a typical floor space located abovethe classification floor indicated at 5, and it will be understood thatthe arrangement of the floor spaces such as is indicated at 14 will beprovided on all the floors of the building above the classificationfloor 5.

The elevator shafts 6 to 10, inclusive, it will be noted, extend throughthe various floors of the garage, the arrangements being such that theelevators 11 will deliver vehicles from the classification fioor 5 toany one of the floors of the building.

Referring now to the elevators, which are, of course, all similarlyconstructed, the floor 13 of each elevator is cut away at the locations13 and 14 so as to provide spaces adapted to receive the traveling belts16 and 17, respectively, said belts being endless. These belts travelover pulleys 18 and 19 mounted upon the shafts 20 and 21, suitablyjournaled on supports provided in the floor 13 of the elevator, theshaft 20 being a driven shaft and the shaft 21 being a driving shaft.Shaft 21 is provided with a pulley 22, which receives a belt 24 drivenas by means of a motor 25 supported in the housing bracket 26, securedunderneath the floor of the elevator. Thus it will be seen that themotor through the shaft 21 drives both of the endless belts 16 and 17,respectively. The upper length of both of the belts rest upon aplurality of rollers 27, which are journaled upon suitable supports.These rollers form a support for the endless belts when the road wheelsof the vehicle to be stored rest upon the belts.

The endless belts are spaced apart to correspond with the lateraldistance between the walls of a motor vehicle and are so disposed thatwhen a vehicle enters the space provided between the walls of theelevator the road wheels will automatically rest upon the belts.Therefore. when the motor 25 is supported, the endless belts willdischarge the motor vehicle from the floor of the elevator on to asupporting and carrying means which will presently be described.

The reference numeral 28 denotes a table or carrier for the motorvehicles. This table or carrier, by means which will presently bedescribed is mounted upon a truck, the construction being such that thetable has a rotary movement independently of the movement of the truckand that the truck and table move in unison in a linear direction. Thetable which is suitably supported for rotary movement on the frame 29 ofthe truck 30, is operated by means of a central shaft 31.

Referring now to Figures 3 to 6, inclusive, of the drawings, thereference numeral 32 denotes a motor which is supported upon a suitablebracket 33, carried by the truck 30. This motor is provided with a shaft34 having mounted thereon a sprocket 35 carrying a sprocket chain 36which drives a sprocket wall 3'7 mounted upon a shaft 38. Shaft 38extends into a transmission mechanism enclosed in a casing 39, andleading from the transmission mechanism, the details of construction ofwhich are not shown herein, is a shaft 40 upon which is mounted thebeveled gear 41. Beveled gear 41 meshes with the beveled gear 42 andthis beveled gear 42 is connected with a shaft 31 which rotates thetable 28. The direction of rotation of the beveled gear wall 41 iscontrolled by the transmission mechanism within the casing 39, theoperation of the latter being determined by a lever 43 having anoperating handle 44. Thus it will be seen that the direction of therotary movement of the beveled gear 41 is determined by the transmissionmechanism within the casing 39.

As will be seen by reference to Figure 10, when the motor 31 is inoperation, the shaft 31 may be rotated in either direcion, the directionof movement being controlled as aforesaid, by the transmissionmechanism. Splined upon the shaft is a clutch member 45, which saidclutch member is operated by a forked arm 46, moved by a link 47, as bymeans of a lever. Provided upon the table and encircling the shaft 32 isa fixed clutch member 48, the teeth 49 of which co-operate with theteeth 50 provided upon the splined clutch member 45. Thus when the lever48 is operated through the connected chain of mechanism, to move theclutch member 45 upwardly the shaft 31 is connected with the table 28 sothat it will be rotated in either direction, the direction of movementbeing dependent upon the direction of rotary movement of the beveledwheel 41 which, as aforesaid, is controlled through the transmissionmechanism within the casing 39.

The reference numeral 51 denotes a worm loosely mounted upon the shaft31. This'worm meshes with the worm wheel 52, provided upon a jack shaft53, journaled in suitable bearings 54, supported underneath the table.The sliding clutch member 45 is provided with a plurality of teeth 55which, when the clutch member is moved downwardly, are adapted toestablish a driving connection through the teeth 56 provided upon theworm 51. When this engagement is made, a driving connection isestablished between the shaft 31 and the worm 51. Mounted on the jackshaft 53 is a sprocket 57, which carries the drive chain 58, the lattertraveling over a sprocket 59 mounted upon the shaft 60, journaled inbearings 61, supported underneath the table 28. Shaft 60 is providedwith the pulley walls 62 and 63, over each of which travels an endlessbelt, said belt being designated by the reference numerals 64 and 65,respectively. These endless belts extend substantially across the tableas shown and travel over the pulleys 66 and 67, suitably journaledunderneath the table 28. The table 28 is formed with slots to receivethese belts. The upper surface of said belts lie substantially flushwith the upper surface of the table and said belts are supported as bymeans of a plurality of adjacently located rollers 68 suitably journaledin bearings provided in the slots of the table. The belts 64 and 65 arespaced apart a distance equal to the lateral distance between the roadwheels of a motor vehicle.

Inasmuch as the direction of rotation of the shaft 31 is controlled bymeans of the transmission mechanism within the casing 39, it will beseen that when the teeth 55 of the clutch member 45 are in engagementwith the teeth 56 provided upon the worm 51, the connected chain ofmechanism will through the shaft 60 drive the belts 64, 65, in eitherdirection, as determined by the operation of the transmission mechanism.

The beveled gear wheel 41 is mounted upon the shaft 66, and this shaft,at one end, is provided with a sliding clutch member 67, and at itsopposite end with a similarly constructed sliding clutch member 68.These clutch members, as shown in Figure 5, are connected together as bymeans of the rod 69 so that they may be moved in opposite directions inunison. The rod 69 is connected to a lever 70, pivoted at 71, theopposite end of said lever having an operating handlewhich extendsthrough an arc shaped slot 72. Thus it will be seen that the clutchmembers 67 and 68 may be slid in opposite directions, in unison, for apurpose which will be presently understood.

The frame 29 of the truck 30 is provided with the brackets 73 and 74,which form bearings for the axles 75 and 76, respectively; upon each ofthese axles, at its other ends, are provided the flanged wheels '7'7--78and 79-80, respectively. The axles 75-76 are spaced apart as shown, eachaxle being journaled adjacent the edge of the table, and the axles arearranged in parallel relation with the motor car supporting belts 64 and65. The wheels 77 to 80, inclusive, ride on the tracks 81 and 82.Mounted upon the axle 75 is a sprocket 83, which is driven as by meansof a chain 84, and the latter is in turn driven by a sprocket 85.mounted upon the shaft 86,

which extends from a second set of transmission mechanism located in acasing 39. This second set of transmission mechanism not shown isoperated through the link and lever mechanism 43 and 44, which havealready been described as controlling the direction of the rotarymovement of the shaft 31. In other words, the construction is such thatthese link and lever mechanisms 43 and 44 may be manipulated so that theoperating motor through the transmission mechanism will rotate the shaft76 in either direction, whereby the axlev75, through the chain ofoperatingmechanism above described, may be rotated in either direction,whereby the truck 30, which supports the table 28, may be moved as awhole along the trucks 81 and 82.

The reference numeral 87 denotes a fixed contact member, in the natureof a third rail, which is mounted upon suitable insulating supports andwhich extends in parallelism with the tracks 81 and 82, and engagingthis contact member is a shoe 88. The contact member 87 is connectedwith suitable source of electric current, not shown, and the shoe 88 isconnected with one pole of the motor 32 as by means of a lead wire 89,the opposite pole of said motor being grounded to the truck.

Thus it will be seen that the motor 32 may be operated to move the truck30 in opposite directions along the tracks 81 and 82.

Referring now to Figures 5 and 6 of the drawings, the reference numeral90 denotes one of the storage spaces for a motor vehicle, it beingunderstood, as shown in Figure 2, that the storage space I is cut upinto a plurality of adjacently located storage spaces similar to thatshown at 90.

By referring to Figure 2 of the drawings it will be noted that thisstorage space is divided into a plurality of sections and each sectionis provided with a plurality of unitary storage spaces such as 90,located adjacent each other throughout the length of the floor space.

In the present instance it will be noted that there are four independentstorage units provided in the typical floor space designated 1, and forthe purpose of this specification these spaces are designated 11, f2, f3and f4, and each of these unitary sections is divided into a pluralityof individual storage spaces such as 90. Between the spaces 11 and I2 isprovided a line of trackage, such as has already been described, assupporting the truck 30, and between the unitary spaces 13 and I4 is asecond line of trackage. Each line of trackage carries one or moretrucks with its rotating table, similar to that which has already beendescribed in Figure 2 of the drawings. Each line of trackage is shownas-being provided with two truck assemblies although it will beunderstood that in practice a greater or lesser number may be employed.It will be seen that by moving the respective trucks along their tracksthe tables may be moved opposite the various individual storage spacesin whidh it is desired to lodge or store a motor vehicle.

Referring now particularly to Figures 5 and 6 of the drawings which showan individual storage space, it will be seen that each space is providedwith a pair of laterally spaced movable belts 91 and 92, respectively,which travel between the pulleys 93-94 and 95-96. The belts aresupported upon the journaled rollers 97 in a manner identical with thatalready described in connection with the traveling endless belts of theelevators. The pulleys 93 and 95, which are mounted upon the shaft 98,journaled in suitable bearings provided in the floor or idler pulleys,and the pulleys 94 and 96 drive the belts 91 and 92, said belts beingmounted upon a driving shaft 99 suitably journaled in the floor. Mountedupon the shaft 99 is a beveled gear wheel 100, which meshes with thebeveled gear wheel 101, the latter being mounted upon the shaft 102,which extends downwardly and has its lower end mounted in a suitablebracket 103. The lower end of shaft 102 carries a beveled gear wheel104, which meshes with the beveled gear wheel 105, mounted upon asuitably journaled shaft 106; the latter shaft, at its outer end, isprovided with a clutch member 107. Thus it will be seen that when theclutch member 107 is rotated, the endless belts 91 and 92 will be drivenin a direction depending upon the direction in whichrotarymotion isimparted to the clutch member 107. The shaft 106 is so located in itsreceptive space 90 that when one of the tables 28 is moved by its truckto such a position that the endless belts 64, 65 of the table are inlongitudinal alignment with the respective endess belts 91 and 92 ofsaid space, one of the clutch members 67 or 68 will be in exactlongitudinal and vertical alignment with the shaft 107, so that, whenthe shaft 66 is moved in an endwise direction by the lever mechanismalready described, one of these clutch members can be engaged with theclutch member mounted upon one of the shafts 107, whereby there may beestablished a detachable operative connection between the drivingmechanism for the endless belts upon the table with the drivingmechanism for the endless belts 91 and 92 of a parallel storage space90. The arrangements of the parts are such that the respective endlessbelts of the table and those of a storage space 90 will move in unisonin the same direction.

Inasmuch as it is desired to move motor vehicles from the endless belts64, 65 of the table 28 to the endless belts 91 and 92 of the storagespace 90 and to move said motor vehicles in an opposite direction, it isnecessary to interpose vehicle supporting connecting platforms betweenthe endless belts of the table and those of the storage space. Thisobject is attained by means of the pivotally mounted saddle plates108-109 and 110-111. Each of said saddle plates is pivotally mountedupon the truck and each pair of saddle plates is spaced apart a distanceequal to that between the endless belts, the construction being suchthat when the endless belts of a table are in exact longitudinalrelation with those of a storage space 90, the saddle plates may beswung downwardly so as to span the space between the ends of the endlessbelts of the table and those of the storage space. Each of these saddleplates 108 to 111, inclusive, is provided with a plurality of rollermembers 112, which provide supporting surfaces across which the motorvehicle to be stored may ride when a motor vehicle is being moved to orfrom one of the storage spaces 90.

In order to hold a truck in the proper operative relation, as abovedescribed, with the storage space, means is provided whereby when atruck has been moved to its proper position it may be locked in suchposition until the operation of moving a motor vehicle to or from astorage space has been accomplished. This object is attained as by meansof a pivotally mounted tongue member 113 on the truck which is adaptedto engage with a slot 114 provided midway of the width of each storagespace, said tongue adapted to be operated by means of a rod 115, theouter end of which is provided with a foot lever 116, by means of whichit may be swung into or out of engagement with any one of the slotsprovided in the storage spaces.

It will be understood that a similar arrangement of pivotally mountedsaddle plates and locking members is provided in connection with theelevator shafts, so that the endless belts of a table may be held inproper registry with the endless belts of each of the various elevatorsserved by a particular truck and its motor vehicle carrying table.

From the foregoing description it will be seen that a motor vehicleentering the classification floor 5 will be driven to a designatedelevator under its own power, and when said motor vehicle has beenproperly positioned upon the endless belts of that particular elevator,the power of the motor vehicle will be then shut off. The elevatorattendant then operates the elevator to cause same to move to its properfloor. The truck serving that particular elevator is then moved alongits tracks so that the table of the truck will be positioned, as alreadydescribed, in operative relation with the elevator, the locking tonguewill be manipulated to center and align the endless belts of the tablewith those of the elevator, and the saddle plates will be swungdownwardly to provide the supporting surfaces, as aforesaid, upon whichthe motor vehicle is to be moved from the traveling belts of theelevator to those of the table.

The motor 25 on the elevator is then operated so that the endless belts16 and 17 will move the motor vehicle across the saddle plates and on tothe endless belts 64 and 65 of the table, the mechanism for the drivingof which has already been set in operation. When the motor vehicle hasbeen properly positioned upon the table, the operation of the endlessbelts is arrested.

The transmission mechanism within the casing 39 is then operated so thatthe mechanism for driving the truck upon its tracks will be actuated ina manner so as to carry the truck to such a position that the tablecarrying the motor vehicle will be directly opposite the particularspace in which the motor vehicle thereon is to be stored. Thecentralizing device between the truck and the storage space is operatedto lock the truck in proper position, and the driving clutch of thetruck is moved into engagement with the driven clutch member of thestorage space. The saddle plates are also moved into their properpositions to span the space between the endless belts of the table andthose of the storage space. The mechanism for driving the endless beltsof the table is again set into operation and through its operativeconnection with the endless belts of the storage space sets the endlessbelts of the latter into operation whereby the vehicle is moved in anendwise direction from the endless belts of the table to those of thestorage space.

When it is desired to" remove a motor vehicle from a space in which ithas been stored, the above described chain of operations is reversed,and the vehicle moved from the storage space to the table of a truck,the truck carried upon its tracks to the elevator shaft and moved fromthe table to the endless belts of the elevator, whereby the 'elevatormay be operated to carry the motor vehicle to the classification floorspace 5, from which it may be driven under its own power from thebuilding.

A pair of posts 117 and 118, is located opposite each of the storagespaces 90, the construction being such that when the bar or gate 116 isin the position shown in Figure 7 of the drawings, that space is lockedagainst the entrance or removal of a motor vehicle. The gate is lockedin the position shown as by means of a latch 119, which engages with akeeper 120, provided upon the post 118. The latch 119 is normally heldin its locked position as by means of an extensile spring 121, whichencircles the stem 122, extending it from the latch, said stem formingthe armature of a solenoid coil 123. This solenoid coil is connected ina circuit formed by the wires 124 and 125, said wires extending to a keyboard 126, the latter being preferably located in an office provided onthe classification floor 5.

Connected in series in the circuit formed by the wires are the electriclamps 127, 128. Lamp 127 is located adjacent one of the storage spacesand lamp 128 is located at the keyboard, it being understood that thereis a lamp similar to 127, located opposite each of the storage spacesand 100 that there is a corresponding lamp 128 for each of the lamps127.

The key board 126 is provided with a plurality of keys 129, therebeing akey provided for each of the storage spaces and each key socket con- 105trolling a lamp and solenoid circuit such as has been described. Eachkey socket is located in the cylinder 130 adapted to receive the key131, and this cylinder when rotated by its key is adapted to operate theswitch 132, and close the circuit 110 formed by the wires 124, 125,which circuit includes the solenoid coil 123. The closing of thiscircuit, energizing as it does the solenoid coil 123, retracts the latch119, whereby the gate bar 116 may be raised.

The reference numerals 133 and 134 denote another circuit, whichincludes the solenoid coil 135, the switch 136 and the lamps 137 and138. The lamps 137 and 138 which are of a color distinguished from thelamps 127 and 128 are located, respectively, lamp 137 opposite a storagespace corresponding to that in which the lamp 127 is located, and thelamp 138 is located adjacent the keyboard.

The switch 136 is normally held open by the weight of the gate bar 116resting upon it. When the first named circuit has been closed toenergize the solenoid coil 123, to retract the latch, the lifting of thegate bar 116 closes the switch 136, thereby closing that circuit, theclosing of which 1 energizes the coil 135, forcing the switch lever 132to the position shown in Figure 11, thus opening the first named circuitwhereby the lamps 127 and 128 will be extinguished.

The lamps 137 and 138 will, however, be lighted, thereby indicating tothe operator at the key board that the gate has been opened, ready toreceive or discharge a motor vehicle from the storage space guarded bythe said gate bar. When the gate bar 116 is. again moved to the positionshown in Figure 7, the circuit controlled by the switch 136 is againopened and the lamps 137 and 138 extinguished. The first named circuit.controlled by the switch 132, will remain open until it is again closedby an operation of 14,5 the key 130.

Thus the lighting of the lamp 127 from the key board advises theoperator on the storage space 4 when and where a motor vehicle is to bestored or removed from storage and the lamp 128 ad- 150
